I've made a couple galleries at http://danandp.wordpress.com and I'm having a problem with the linked-to photos. The galleries and thumbnails are fine, but when clicked, the photo that comes up is much too small. My originals that i'm uploading are much larger (900x650ish). I've seen other wordpress galleries where you click the gallery thumbnail and it takes you to a page w/ a nicely size pic. From there you can click again to see it in full size.
How do I do this?
